DESCRIPTION FOR SQL INJECTION
#####################################################
  
An attacker might execute arbitrary SQL commands on the database server with this vulnerability.
User tainted data is used when creating the database query that will be executed on the database management system (DBMS).
An attacker can inject own SQL syntax thus initiate reading, inserting or deleting database entries or attacking the underlying operating system
depending on the query, DBMS and configuration.
 
POC:
